Abstract

Certain examples of the present disclosure relate to controlling the transmission of Semi-Persistent Scheduling Hybrid Automatic Repeat request Acknowledgment, SPS HARQ-ACK, and Physical Uplink Control Channel, PUCCH, repetitions. Some examples provide an apparatus configured for: determining Discontinuous Reception, DRX, timing information, wherein the DRX timing information is indicative of at least one time period of cell DRX inactivity; determining PUCCH resource information (205), wherein the PUCCH resource information is indicative of a PUCCH resource for the apparatus to transmit a SPS HARQ-ACK; and controlling a transmission of the SPS HARQ-ACK based at least in part on the DRX timing information and the PUCCH resource information.
